Název v původním jazyce

Laser-Driven Acceleration of Charged Particles

Popis výsledku v původním jazyce

Laser-plasma particle accelerators are currently receiving particular scientific attention as promising source of accelerated charged particles, since they are able to generate much stronger electric fields in comparison with conventional accelerators and can possibly replace them in future in several impressive applications, including proton therapy for the treatment of the cancer cells, production of PET (positron emission tomography) medical isotopes, generation of ultrashort neutron pulses, radio isotope source or high-energy electron radiography and radiotherapy. Currently, laser-driven particle acceleration still needs to face several challenges, like further improvement of produced particle beam quality and properties. Therefore, two novel schemes for ion and electron acceleration were investigated in this project. 1.) Interaction of high-intensity laser pulse with thin overdense double layer targets with initial corrugation on the interface, resulting in generation of high-density proton bunches, exhibiting mono-energetic behavior. 2.) Interaction of high-intensity laser pulse with nitrogen gas targets for controlled production of ring-shaped electron beams. We performed several demanding 2D and 3D simulations and demonstrated the mono-energetic behavior of accelerated protons and explained the mechanism responsible for generation of the ring-shaped electron beams analytically and via simulations.
